Figure 4. Effects of LyA and OGD on cell viability. (A) Cells were incubated in different concentrations of LyA alone. (B) MTT assay was employed to investigate the protective effect of LyA against OGD-induced cytotoxicity. (C) Cell death was further confirmed by measuring LDH leakage. Data were represented as means ± SD (n=6). *p < 0.05 compared with control group; #p < 0.05 compared with OGD group.
